Overview
Disodium citrate dihydrate is a sodium salt of citric acid with buffering and chelating properties. It serves as a versatile reagent in various research fields, including electrochemistry, biochemistry, and analytical chemistry. Its ability to sequester metal ions and maintain stable pH makes it valuable in both laboratory and industrial applications.

Applications

• Electrochemical research: Used in studies on mediator‑less laccase cathodes as a half‑cell electrode component under galvanostatic load using a two‑chamber setup.

• Biological sample preparation: Employed in the extraction of organ and tissue samples, facilitating preservation and processing.

• Buffering agent: Provides stable pH control in biochemical and analytical applications.

• Chelating agent: Binds metal ions, preventing interference in enzymatic and analytical systems.

• Anticoagulant: Used in blood collection and storage as a mild anticoagulant.

• Food and pharmaceutical industries: As a stabilizer, antioxidant synergist, and acidity regulator.

Key Properties

• High purity (≥99%) ensures reproducible results in sensitive experiments.

• Excellent water solubility for easy preparation of solutions.

• Mildly alkaline pH in solution, suitable for maintaining physiological conditions.

• Stable under normal storage conditions; non‑hygroscopic.

Handling and Storage

• Store in a cool, dry, well‑ventilated area, away from strong acids and oxidizers.

• Keep containers tightly sealed to prevent contamination and moisture absorption.

• Use appropriate personal protective equipment (gloves, safety goggles, lab coat) when handling.

• Avoid inhalation of dust; wash hands after handling.
